Maranao (Filipino: Wikang Mëranaw; Jawi: باسا أ مراناو), sometimes spelled as Maranaw, Meranaw, or Mëranaw, is an Austronesian language spoken by the Maranao people in the provinces of Lanao del Sur and Lanao del Norte and their respective cities of Marawi and Iligan located in the Philippines, as well found also in Sabah, Malaysia. It is spoken among the Moros within the Bangsamoro Autonomous Region in Muslim Mindanao.
It is more closer to Iranun than to Maguindanao within the Danao subgroup.
The Autonomous Region in Muslim Mindanao (Filipino: Rehiyong Awtonomo ng Muslim Mindanao; Arabic: الحكم الذاتي الاقليمي لمسلمي مندناو Al-ḥukm adh-dhātī al-'iqlīmī li-muslimī Mindanāu; ARMM) was an autonomous region of the Philippines, located in the Mindanao island group of the Philippines, that consisted of five predominantly Muslim provinces: Basilan (except Isabela City), Lanao del Sur, Maguindanao, Sulu, and Tawi-Tawi. It was the only region that had its own government. The region's de facto seat of government was Cotabato City, although this self-governing city was outside its jurisdiction.
The ARMM included the province of Shariff Kabunsuan from its creation in 2006 until July 16, 2008, when Shariff Kabunsuan ceased to exist as a province after the Supreme Court of the Philippines declared the "Muslim Mindanao Autonomy Act 201", which created it, unconstitutional in Sema v. COMELEC and Dilangalen.
The Iranun language (Jawi: إيراناونساي), also known as Iranon or Illanun, is an Austronesian language belonging to the Danao languages spoken in the provinces of Maguindanao del Norte and other part of Lanao del Sur and Lanao del Norte, coastal municipalities of Zamboanga del Sur from Tukuran to Dumalinao, and Cotabato in southern Philippines and the Malaysian state of Sabah. It is the second most spoken language in Maguindanao del Norte after the Maguindanao language.
